Establishing an effective compliance program has become an important way for western companies to conduct internal corporate governance. We can regard compliance management,business management and financial management as three major components of contemporary corporate governance.However,the reason why western companies have a strong incentive to establish a compliance program is that there are multiple incentives in criminal law. If an effective compliance program could be established,companies which were suspected of committing crimes can seek for non-prosecution,plea for innocence,obtaining penalty reduction,and even gaining an important basis for signing a deferred prosecution agreement with the regulatory authority. In this case,companies can minimize their losses. It is also under the influence of this criminal law incentive mechanism that the western law firms have gradually developed three important kinds of compliance business,including independent compliance investigations,response to regulatory prosecutions and building compliance programs. We can completely understand corporate compliance only when it is seen as a method of corporate governance,an incentive mechanism in criminal law,and a part of lawyer’s business which assists companies in preventing legal risks.
